Is this weird?

When my boyfriend and I have oral sex and he is eating me out, I always find it a HUGE turn on when he bites my clit. Before anyone says that it may not be safe, he doesn’t do it too hard but hard enough for me to feel pleasure and pain. I find pleasure in pain when it comes to sex. I love it when he bites my nipples, spanks my pussy, spanks my ass hard enough to leave a handprint and gets rough with me. He ALWAYS give me after care and treats me like a princess. I’m lucky to have him but if what I like weird or unnatural?
